Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-30S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-30S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 900mm stroke, G1 air ports and adjustable end cushioning. Its large-bore tie-rod build delivers high thrust and drops into standardized ISO 15552 mounting on heavy automation.

About the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-30S
Delivering massive thrust for heavy industrial tasks, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. Four steel rods clamp the aluminium barrel to the covers, and the G1 air port feeds a 50 mm piston rod. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 870 to 900 mm without changing the mount.
Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. The -S suffix adds a piston magnet for CMSG, DMSG, or EMSG switches. It handles a safe working load of about 14726 N, lifting roughly 1251 kg vertically with a 2:1 margin. Note that TPU seals are unavailable here; NBR is standard, with a Viton H option for 0 to 150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-30S Is Used
Heavy Press Tonnage
Provides raw clamping force for large metal forming presses, using the 30 mm stroke adjuster to dial in exact material thicknesses on-site.
Pallet Lift Carriage
Raises heavy automated pallet carriages, where the 900 mm stroke offers deep vertical reach and the magnetic switches track position.
Mold Stage Alignment
Slowly extends and seats heavy injection molds, using the adjustable air cushions to decelerate the massive payload smoothly.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-30S the Right Cylinder?
When sizing this unit against neighbours, a 200 mm bore yields 15708 N push at 0.5 MPa, whereas this 250 mm bore hits 24543 N, representing the top standard capacity. The 30 mm adjustable window is perfect for tuning end positions on-site or sharing a spare across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S magnet supports CMSG/DMSG/EMSG sensors. Because the stroke is 900 mm, you must use external guides to prevent rod bending under side loads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-30S FAQ
At 0.5 MPa it pushes 24543 N and pulls 23562 N. At 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa.
An external adjuster shortens the extend stroke by up to 30 mm on-site, giving a usable extend range of 870 to 900 mm. The nominal 900 mm stroke is the maximum. The retract end is fixed. This mechanism sets the end position and is not a load lock; use an external rod lock to hold loads.
